* lib, ipcpd: piggyback ECDHE on flow allocationDimitri Staessens2020-02-252-0/+4
| | | | | | | | | | | The initial implementation for the ECDHE key exchange was doing the key exchange after a flow was established. The public keys are now sent allowg on the flow allocation messages, so that an encrypted tunnel can be created within 1 RTT. The flow allocation steps had to be extended to pass the opaque data ('piggybacking').

| | | | | | | | | | | | | | | | | | This replaces the time utility functions with macros. This avoids using library functions in the tools and also slightly speeds up the implementation.

* tools: Add quiet option to opingDimitri Staessens2018-06-062-18/+32
| | | | | | | | | This adds a --quiet -Q option to oping so it will only print the statistics summary. Also fixes a division by 0 if duration is specified with interval 0. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>

* tools: Add out-of-order statistics to opingDimitri Staessens2018-06-052-3/+16
| | | | | | | | | This adds out-of-order statistics to the oping tool. A packet is considered out-of-order if its sequence number is lower than the highest sequence number already received.

| | | | | | | | | This adds a timestamp option to oping, similar to the one in regular ping and rinaperf, so that we can more easily correlate time and latency. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>

* tools: Disable partial reads in opingDimitri Staessens2018-05-072-3/+6
| | | | | | | | | The oping tool was using a 1500 byte buffer, but didn't account for partial reads when sending 1500 byte packets. This disables the partial reads. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Use non-blocking read in serversDimitri Staessens2018-03-161-1/+1
| | | | | | | | | | | The oping and ocbr servers were using non-blocking read/writes. This caused writes to fail on high-performance tests if the buffer got full, instead of waiting for a slot in the buffer. The write failure caused the server to quit. This fixes the tools by setting the I/O to blocking write and non-blocking read.

* lib: Use PTHREAD_COND_CLOCK for blocking reads0.10.6Dimitri Staessens2018-03-101-2/+5
| | | | | | | | | | | The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE clock. This causes the blocking reads not to timeout correctly. The oping was updated to detect server timeouts and finish gracefully.

* tools: Don't cancel reader thread in oping0.10.5Dimitri Staessens2018-03-051-2/+0
| | | | | | | | The reader thread was cancelled as soon as the writer was finished, which resulted in missed responses and misreported packet loss. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* build: Allow out-of-tree build of toolsDimitri Staessens2018-02-144-27/+25
| | | | | | | | | | This removes the dependencies for the tools on some ouroboros internal headers (endian.h and time_utils.h) so they can be built out-of-tree. The echo-app tool has been renamed oecho and the cbr tool has been renamed ocbr.

* build: Use GNUInstallDirs instead of hardcoded values0.9.9Sander Vrijders2018-02-061-1/+1
| | | | | | | | This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>

* tools: Fix SEGV in oping clientDimitri Staessens2017-11-221-4/+8
| | | | | | | | | | | The oping client tried to cancel non-created pthreads if it was killed during flow allocation, which caused a SEGV. The threads are now stopped using a variable. Fixes bug #2.

* tools: Change license to 3 clause BSDDimitri Staessens2017-10-243-30/+78

* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-142-14/+1
| | | | | | | | | | | | | | This commit deprecates ouroboros_init and ouroboros_fini and adds them as a constructor or destructor, causing these function to be run automatically when a program that links to the library calls and exits main(). For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common.
* lib: Add fccntl configuration commanddimitri staessens2017-08-312-3/+3
| | | | | | | This replaces the flow_set_* commands with a single fccntl command that can configure flows and the FRCT instance. For more details, see "man 3 fccntl".

* build: Revise the build systemdimitri staessens2017-08-214-8/+3
| | | | | | | | | | This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.

* lib: Revise flow allocation APIdimitri staessens2017-03-312-19/+5
| | | | | | The flow_alloc_res and flow_alloc_resp calls have been removed. The flow_alloc and flow_accept calls are now both blocking and take an additional timeout argument.
* Change email addresses to ugent.beSander Vrijders2017-03-033-6/+6
| | | | | | | Our mailserver was migrated from intec.ugent.be to the central ugent.be emailserver. This PR updates the header files to reflect this change as well. Some header files were also homogenized if the parameters within the functions were badly aligned.

* tools: Continue oping server after failed writedimitri staessens2017-02-221-3/+1
| | | | | | When hammering the oping thread, it will have write fails when the buffer gets full as its flow is non-blocking. It would stop and deallocate the flow, but should just continue.
* tools: Fix overflow bug in opingdimitri staessens2017-02-221-9/+10
| | | | | | Sometimes the receiver thread got the SDU before the writer thread has set the sent time when testing over the local. The sent time is now written before actually sending to avoid this.
* build: Update licenses and copyrightdimitri staessens2017-01-093-3/+3
| | | | | Copyright is set to 2016 - 2017. License text on includes and sources in the library are changed to indicate the LGPLv2.1 license.

* src, tools: Set/get timeout and get qos for flowsdimitri staessens2016-12-123-76/+46
| | | | | | | | | | | | | | | | Receiver timeouts can now be set on a flow using the flow_set_timeout function. Specifying NULL disables the timeout. The flow_get_timeout function gets the value for the timeout. This commit also deprecates fcntl in favor of flow_get_flags and flow_set_flags functions. struct qos_spec is typedef'd as a qosspec_t. The tools and cdap.c are updated to use the new API. Fixes a bug in operf client where the client's writer thread wouldn't cancel on SIGINT.
* tools: Fix compilation issues on 32 bit machinesdimitri staessens2016-12-022-7/+8
| | | | | | size_t is 32 bits on those machines, failing as an argument to printf. Some variables in oping and operf were changed to uint32_t and uint64_t to avoid issues.

| | | | | | | | | If alloc_res fails all resources will be cleaned, except for the assigned flow_descriptor, which must be released with a dealloc call. Calling dealloc after a failed flow_alloc will not try to destroy the already cleaned up flow in the IRMd and IPCPs. Also fixes some memleaks in the oping client.
